PD Particles - feedback? samples?

Heya all, PD Particles has been available here for about a month, I was wondering if anyone who's got it has any constructive feedback, criticism, bits of encouragement or other info you could share? We're particularly interested in any specific reqests for improvements, and bug reports, or oddities that may point to unknown shortcomings we should like to check into. Please post them here so we may best serve this community with an open discussion on what's hot and what's not in PD Particles.
